Replace a Worn or Damaged Factory Linkage

The rear suspension linkage operates under constant load as the suspension moves through jumps, braking bumps, whoops, rocks and rough terrain.

After years of use, the original linkage assembly may develop:

• Worn bearings
• Damaged seals
• Excessive movement or looseness
• Corrosion
• Worn mounting surfaces
• Inconsistent suspension action
• Poor rear-suspension response

Replacing a worn linkage helps restore proper movement and dependable operation throughout the rear suspension system.

CNC-Machined 6061-T6 Billet Aluminum

Each Basic Dimensions linkage is machined from high-quality 6061-T6 billet aluminum for consistent dimensions, accurate fitment and dependable durability.

Compared with a conventional cast component, billet construction provides:

• Consistent material structure
• Precise mounting surfaces
• Accurate bearing bores
• Excellent rigidity
• Resistance to bending and deformation
• A clean, high-performance appearance

The linkage is designed to retain the intended suspension geometry while providing a durable replacement for an aging or damaged original component.

Bearings and Seals Arrive Pre-Installed

Suspension-linkage service often requires a bearing press, drivers and careful seal installation. This linkage arrives with the necessary bearings and seals already installed.

Installation Advantages

• No bearing press required
• No separate bearing kit to purchase
• No seal installation
• No additional assembly
• Reduced installation time
• Ready to bolt onto the motorcycle

Lubricate all mounting bolts and bearing surfaces according to the Kawasaki service-manual specifications during installation.

Direct Bolt-On Replacement

The Basic Dimensions rear linkage installs in the original mounting location using the motorcycle’s factory linkage bolts and related hardware.

No cutting, welding or permanent frame modification is required.

Before installation, inspect the following components:

• Linkage mounting bolts
• Collars and sleeves
• Swingarm bearings
• Lower shock bearing
• Frame mounting points
• Fastener threads
• Grease seals

Replace any worn or damaged hardware before operating the motorcycle.
